ESLint configuration not applied to files outside root src/ directory

Note

This issue was created programmatically via GitHub CLI.

Problem

ESLint configuration was not applied to files outside the root `src/` directory, causing those files to be linted without a proper parser. Additionally, JSX parsing was not enabled for JavaScript files.

Root Cause

1. File Pattern Issue: The original `files` pattern `src/**/*.{js,jsx,ts,tsx}` only matched files in the root-level `src/` directory. Files in other directories (e.g., `Hyperswitch-React-Demo-App/src/`) were not covered.

2. Missing JSX Parser: JSX parsing was not explicitly enabled. ESLint's default Espree parser does not understand JSX syntax unless `ecmaFeatures.jsx: true` is configured.

Proposed Solution

• Broaden file pattern to `**/*.{js,jsx,ts,tsx}` to cover all JS/TS files in the project
• Enable JSX parsing via `ecmaFeatures: { jsx: true }`

Acceptance Criteria

• ESLint runs correctly on all directories
• JSX syntax is properly parsed in JavaScript files
